Abstract

The invention discloses a surgical tool for cartilage injury, wherein the surgical tool includes a rod part; the rod part includes a first section and a second section; the first section is used for receiving rotation driving, and the end of the second section is provided with a spherical head; the first section is provided with a first wedge-shaped part, the end of the second section is providedwith a second wedge-shaped part, the first wedge-shaped part and the second wedge-shaped part are matched to achieve the rotation transmission of the first section to the second section. The surgicaltool also includes an elastic part; two ends of the elastic part are respectively connected with the first section and the second section, and the deformation force of the elastic part is set as thatwhen the resistance between the first section and the second section is greater than the preset value, the second section is separated from the first section to drive the elastic part to deform. According to the surgical tool for cartilage injury provided by the invention, the rod part is set into two sections and the middle part is subjected to transmission by the two wedge-shaped parts. When theresistance is large, the two wedge-shaped parts are separated to realize decoupling of the transmission; through reasonable pressure selection, the spherical head can remove damaged cartilage and bestuck when encountering normal cartilage.
